Designed for applications requiring high flow in an extremely compact package, especially in the medical, automotive, and business equipment markets, the new durable, oil-less Model 1420 pump achieves higher flows than conventional standard diaphragm pumps of the same physical size. The pump measures 3.41 inches long × 1.16 inches wide × 2.96 inches high, and weighs .485 lbs. Flow is rated at 6.0 to 11.0 lpm, when the heads are in parallel configuration, and up to 5.5 lpm in series configuration. The maximum pressure rating is 1 bar, and the maximum vacuum rating is 23 inches Hg. The Model 1420 pump is available in both 12 and 24V dc versions and incorporates long-life EPDM (ethylene-propylene rubber) diaphragms and valves.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
